A description of what the graph is about BUT you cannot use the language in the question because the examiner won’t count the words if you do.

What is the graph about?

It is about the percentage of people who were unemployed in the USA and Japan over a period of 6 years from 1993 to 1999.

In fact, it compares the unemployment figures in the two countries, so we could write as an introduction:

The chart compares the percentages of people who were unemployed in the USA and Japan over a period of 6 years from 1993 to 1999.

We can shorten this a little (I always write too much – your target is 170 words ) to:

The chart compares the percentages of people who were unemployed in the USA and Japan from 1993 to 1999.

There is a free bonus here, look what we managed to do without really trying, the clause:

“who were unemployed”

is a a relative clause structure with “who”, it is a complex sentence and that will get Band 6 minimum and Band 7 or higher depending how often the grammar is correct.

So what have we achieved?

We have written an introduction in our own words so the examiner will count ALL the words in the essay word count, AND we have created a complex sentence with a relative clause that, in the VERY FIRST sentence, will have the examiner thinking ‘minimum band 6’.

We really should do a few exercises on this before moving on to the next part.
